NCP3231GEVB - High Current Synchronous Buck Converter

Overview

TopologyBuck Converter
IC revision1

Description

The NCP3231 is a high current, high efficiency, voltage−feed− forward voltage−mode synchronous buck converter which operates from 4.5 V to 18 V input and generates output voltages down to 0.6 V at up to 25 A DC load or 30 A instantaneous load. It has a 500kHz switching frequency while having a good thermal performance. It also has hiccup mode operation for all faults.
